现在对牙齿问题的评估是在临床和放射学上进行的。后者包括基于x射线辐射的x线摄影，即口内x线摄影、全景x线摄影和三维（3D）锥束计算机断层摄影（CBCT）。在一些情况下，x光片有局限性，因为它们不能显示牙齿问题，如小蛀牙、牙釉质裂缝或牙齿侵蚀。这些方面可以通过另一种医学成像技术，光学相干断层扫描（OCT）看到。本研究的目的是介绍一些使用内部开发的扫描源OCT （SS-OCT）系统在几个牙科问题上获得的结果，这些问题在x光片上无法看到。这些结果证明OCT具有无辐射、分辨率高等优点，可以应用于牙科领域。本研究展示了不同牙齿问题的x线摄影和OCT图像，包括小洞，金属冠裂缝，或由不同材料制成的冠（即氧化锆，陶瓷或复合材料）。首先，对样本进行放射学分析，可以检测到一些异常，但可以正确评估。其次，用SS-OCT系统分析这些异常，最后将两种医学成像技术的所有图像和收集的数据进行比较。其中一个结论是，OCT比x线摄影更适合于一些牙科问题，例如本研究中提出的问题。因此，这两种医学成像技术可以在牙科医学中互补。
The assessment of dental issues is done nowadays both clinically and radiologically. The latter includes radiographs that are based on X-ray radiation, i.e. intraoral radiography, panoramic radiography, and three-dimensional (3D) cone beam computed tomography (CBCT). In several cases, radiographs have limitations, as they do not reveal dental issues such as small cavities, enamel cracks, or tooth erosion. These aspects can be visible with another medical imaging technique, Optical Coherence Tomography (OCT). The aim of this study is to present a few results obtained with an in-house developed swept-source OCT (SS-OCT) system on several dental issues that cannot be visible on radiographs. These results prove that OCT can be utilized in dentistry, with advantages such as radiation free technique and superior resolution. This study presents both radiography and OCT images for different dental issues which include small cavities, metal crowns cracks, or crowns manufactured with different materials (i.e., zirconia, ceramics, or composite). Firstly, samples have been analyzed radiologically and some abnormalities could be detected, but they could be correctly assessed. Secondly, these abnormalities have been analyzed with the SS-OCT system and finally all images and collected data from both medical imaging techniques have been compared. One of the conclusions is that OCT is more appropriate than radiography for several dental issues such as those presented in this study. These two medical imaging techniques can therefore be complementary in dental medicine.
